Patented June 4, 1935 UNH'EED STATES PATENT QFFHCE mosses an'r'rsa PACKAGE AND ivis'rnon or SAME My invention relates to packaging butter, and includes both the form and arrangement of the blocks or bricks of butter, and also the means and method by which such arrangementis made possible and by which it is made permanent throughout the process of handling, from producer, through dealer to consumer. 1

I accomplish the objects of the invention in the manner illustrated in the accompanying drawing, in which Figure l is a perspective of a single block or brick of butter;

Figure 2 is a perspective view showing the arrangement of the blocks in the open carton,

with a base row consisting of three blocks arranged alternately so that the base of the middle block faces upwardly and forms a base for supporting a single block above-the assembly presenting, at the end, the appearance of a triangle of the same shape as the individual blocks; Figure 3 is a perspective view of the package as it appears when the carton is closed.

Similar numerals refer to similar parts throughout the several views.

Referring to the drawing, a single brick or block of butter is in the form of a triangular prism as illustrated in Figure 1. It has two end surfaces 5,, and three side faces or facets t, l, and 8. In cross-section, these blocks are equilateral triangles. The particular facet on which the block rests at any moment may be regarded as the base. The length of the prism varies but ordinarily is approximately two and one-half times the width oi one of the facets. It will be noted that when the butter is bein marketed, each block will be separately wrapped, for example, in oiled or waxed tissue paper, or other appropriate wrapping.

In packaging the butter, the blocks are arranged as illustrated in Figure 2, with three blocks arranged side by side in the base row. They are placed alternately, so that the middle block stands upon its apex, and one of the facets lies horizontally on a plane with the apices of the adjacent blocks. The fourth block is placed upon the middle block of the base row, with its base facet resting upon the up-tumed facet of the middle block. The "result is that the assembly produces an equilateral triangle of the same general shape as the individual blocks. The blocks are held in this relation by means of a carton which has a central section l0, and two side sections l2, IS. The central section is of the size and shape of the base of the composite triangular prism Just described. The side sections l2, it, which are hinged to it, are or the size and shape of the sides of said composite prism, thus reaching to the apex thereof when the carton is closed. The side section ll has a pasting strip tor pasting against the upper 5 edge of the opposite sidesection l2, when the carton is closed. The central section it has two end flaps ii, for covering the ends of the assembled prism. The section "has two end flaps '58 for overlapping the flaps it. when the carton is closed, and the section I! has end flaps for overlapping the sections !8 when the carton is closed. The flaps 20 have tongues 22 for entering slots 24 formed in the flaps IQ for holding the carton closed. Thus, the closed 1 carton with its contents, presents the form of a triangular prism, which, in the present instance, is an equilateral triangular prism, resulting from the fact that the individual blocks themselves are equilateral. It is not essential, 20 however, that the triangular ends be equilateral,

as they may be in the form of isosceles triangles,

in which event the carton itself will have a corresponding form.

It will be observed that a carton constructed 25 in accordance with' my invention has but three main foldable sections instead 01' the more usual number of four. The blocks of butter when sliced at right angles to the length of the prism, produce butter patties of triangular outline. Consequently, they give the appearance of being larger than four-sided patties having the same weight and thickness. That is to say, a patty c! a given bulk and thickness will appear larger when having only three sides than it the outline were rectangular. It will also be observed that the complete package has four prismatic blocks, which is the usual number packed in a single carton in accordance with current practice, and yet with my construction and arrangement the carton requires but three main sections.

I claim: I

l. A butter package including a plurality of identical blocks of butter, each m the form of an equilateral triangular prism, the blocks being arranged with at least one facet of each contiguous to and cc-extensive with a facet of another block. I

2. A butter package consisting of tour identical blocks of butter, each in the shape of a triangular prism, the blocks being arranged with a base row of three blocks alternately placed so the base of the center block will-lace upward, the fourth block being centrally placed on the center block of the base row, to thereby form an assembly which in itself constitutes a triangular prism and in which said center block is completely encircled by said other blocks, and means for holding the blocks in the relative positions described.

3. A butter package comprising four identical blocks of butter, each in the shape of an equilateral triangular prism, the package having three of the blocks arranged in a base row in alternate relation, whereby one of the facets of the center block faces vertically upward, the fourth block forming the apex portion of a composite prism of the same shape as, but greater size than the individual blocks, and a carton for holding the blocks in this relation.

4. A butter package comprising a triangular composite prism composed of four equilateral one of said sections for holding the carton closed 10 circumferentially, two adjacent sections of the carton having end flaps to cover the ends-of the composite prism, one of the end flaps having a tongue and the other a slit for the reception of said tongue for holding the end flaps closed.
